    NGC 4562

    Hi everyone,

    Last evening I was out for a relaxed observing session using my Tak FS128, under very good conditions in rural skies. As NGC 4565 was nearly overhead at the time and it is one of my favorite galaxies, I natuarally spent some time on it. Well, the major surprise was not 4565 itself (which was glorious as usual), but NGC 4562 (or 4565A as some sources call it), the faint galaxy at the end of the curving line of 11 and 12th mag stars to the west of 4565. I was not looking for it, as I did not expect to see it in the 128, having failed to detect it before in my 6" and 5" achromatic refractors. Yet, there it was, faint but umistakeable, easy with averted vision, and after covering my head with my DSA hood, held steady even with direct vision. It was a major surprise, as most sources list this galaxy as anywhere from 13 to 14th magnitude, and, although under relatively dark skies, I was far from observing under really dark conditions (my backyard SQM readings hover around 21.0).

    NGC 4562 is an easy catch of course using my 18", but according to my notes I failed to detect it with my old 12" (of course I was less experienced then). A quick search indicated very few observations, and all of them with 12 or more inches, with the single exception of O' Meara's observation using a 4" in his Caldwell book. Has anyone else observed this galaxy in a smaller aperture? I will post a sketch tomorrow as I have yet to digitize my drawing.

    A great catch with such a small aperture! NGC 4562 is missing from my drawing I made with my 4" f/4 Newtonian. So I didn't see it. But I didn't particularly look for it either. My drawing from 2012:

    Hi Rolandos,

    interesting challenge. I will take my 72 mm refractor and try my best to see anything under rural to alpine skies as soon as possible.

    My drawing from Friday evening. NGC 4562 is barely visible on the original drawing, I hope it makes it to your screens.

    After Friday I believe it is possible in a good 4". Peter, I think you need more magnification than you used in your 4". Norman, for 72mm under alpine skies probably doable. It is amazing what can be seen under good conditions even in tiny apertures...

    Holy moly you need averted vision to see it.

    Great drawing I know it is hard to draw a object and show it at the limit of visibility. Good Job!

    :-) NGC 4562 becomes visible when scrolling up and down ;-)

    Indeed Rolandos, tiny apertures are often underrated. At least stellar magnitude is around 13mag with my 72 mm... so worth a try ;-)
